Ethological studies in Swiss albino mice with special reference to the histology of the cerebellar tissue after an acute as well as a continuous low–dose tritiated water (HTO) exposure
Health and environmental impact of tritium released from fusion reactor technology may end up as a worldwide problem in the final analysis. Pregnant Swiss albino mice were irradiated with 11.1 kBq ml−1 tritiated drinking water. The young ones born to them were maintained on tritiated water (HTO) at the same dose level and in adulthood, when tested in a maze showed an apparent increased learned ...

Low natural terrestrial radioactivity in oil–derived lubricants
Oil and gas production processing operations have been known to involve naturally occurring radioactive materials that lead to internal and external radiation hazards and thus a significant radiation dose to the workers. In this work, samples of nine oil lubricants used on a daily basis were collected from local suppliers in Egypt and analysed to determine their natural radioactivity. The ...

A Monte Carlo simulation of a whole body counter
The preparedness of response to the accidental incorporation of radionuclides into the human body by inhalation or ingestion is a subject of major concern due to the generalised use of ionising radiations in medical and industrial applications. Following a radiological or nuclear accident or in case of occupational exposure due to an accidental dispersion of radionuclides, a rapid methodology is ...

Quantitative Uncertainty Analysis of Superfund Residential Risk Pathway Models for Soil and Groundwater: White Paper
1. INTRODUCTIONThe quantitative assessment of uncertainties in the exposure parameters for the individual exposure pathways provides considerable information about the variability and sensitivity of the calculated results. These results are important because point estimates of these parameters are used to determine the extent of remediation necessary through the Superfund process. The point ...

Radiation doses due to natural radioactivity in the Afra hot springs, Jordan
This paper briefly reports some data from investigations carried out in the Afra hot springs, 160 km south of Amman, Jordan. These data emphasise the new findings of high-radiation dose equivalents, mainly to identify the potential and known impacts of exposure on public health in High Levels of Natural Radiation Areas (HLNRAs) of this region, and also to make recommendations for further studies. ...

Radionuclide content of human samples in the Ramsar area of Iran
As part of a survey to determine public exposure to natural radiation and to estimate radionuclide levels in the diet and human tissues, the radionuclide content of different biological samples of residents in Ramsar, a high level background radiation area (HLBRA) in Iran, has been measured. The main route of 210Po and 210Pb intake in the human body is ingestion via foodstuffs. The absorption of ...

Ionising Radiation
Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...
